🔧 Debug: Interpolated Sliding Window Animation

What to Look For:

Expected Behavior:

Frame 1: Line starts at x=[0,1,2]

Frame 10: Line has grown to show x=[0,1,2,3] approximately

Frame 20: Line slides to show x=[2,3,4,5] approximately

Final Frame: Line ends at x=[6,7,8]

Manual Test Instructions:

  1. Click the ▶ play button to start animation
  2. Watch carefully - do the line coordinates change smoothly?
  3. Use the slider to manually scrub through frames
  4. Check if early frames vs late frames show different data
